Description

密码防盗车锁
目前使用的车锁,都是锁车后拔出钥匙的传统方法,钥匙孔露在外面。容易用万能钥匙开锁窃车,防不胜防。
本实用新型的目的是设计一种安全性强,能防止用万用钥匙打开的新型车锁。
本实用新型的目的是这样实现的:1、锁链的一端固定连接密码锁头,另一端固定连接钥匙。密码锁头的正面有几个小窗口,露出部分带数字的密码圆轮,圆轮与锁心开启机构相连,锁头的一个侧面有一个与钥匙形状相应的钥匙孔,拨动锁头的密码圆轮控制锁的开启。锁车时,将钥匙插入钥匙孔里,拔乱密码车即锁住,因钥匙插留在钥匙孔里的,这就杜绝了用万能钥匙开锁窃车的可能性。拨动密码圆轮使其密码与原予设的密码相同时,钥匙可以拔出锁也就打开了。2、每个锁的密码可达几百万个,不知道密码开锁率是几百万分之一,保密性能。3、锁链是采用钢丝绳索,或粗钢条,或钢条制成的连环锁链,在一定时间内,不用电动工具是难以破坏的,坚固性好。
下面结合附图和实施例对本实用新型进一步说明:
图一是密码防盗车锁第一实施例(自行车、摩拖车锁)构造示意图。
图二是密码防盗车锁第二实施例(汽车方向盘锁)结构示意图。
